Application led January 2,

To aZZ uzom z't may concern: y

Be it `known that I. FRANK E. RIC-E, a

and State of Michigan, have invented certain new and useful Improvementsin Adjustable Flange-Bushings, of which the f'iollowing is a.specification, reference b eing had therein to the accompanyingdrawings.

In the adjustment for bushes for receivmg taps for drawing of'thecontents of metal packages, such as enameled or glass lined heer kegsand the like, it is advantageous 'that the parts be so disposed as topermit adjustment for variation in the thickness of a. receptacle wall.

rIbis invention relates to a bushing for securing a tap in a metallicpackage and toV an arrangement thereof whereby the bush is adaptable foruse with insulated and enameled or porcelain lined walls of varyingthicknesses.

The invention consists in the matters hereinafter set forth andparticularly pointed out in the appended claims.

In the drawings, Figure l isa plan view of a portion of a. packageequipped with a bushing that embodies features of the invention; Fig. 2is a. view in detail and transverse section of -a port-ion of thepackage and the bushing.

As herein shown in preferred form, a

package, illustrated as a. beer keg, has an outer metallic 'shell 1 andan inner metallic lining Q separated by suitable insulating.

materials 3, such as cork or the like, and arranged to' be enameled-onthe inner face, of the lining. A bushing body 4 that has a recessedouter face, is secured in an open-i ing through the outer wall 1 and thelining 3 with an exterior marginal flange 5 seated against the outerface of the outer lining. A nipple 6 is arranged in Screwthreadedengagement with a central opening in the inner end portion of^thebushing body with-a slightly reduced innerportion 7 extending through amating opening in the lining 2. The bore of the nipple is ar-4 ranged toreceive the tap tube and 1t has on its outer end portion interruptedflanges 8 or the like holding means by which a tap may be secured when atap tube is inserted to prevent leakage. The inner portion 7 of thenipple and the outer flange 5 of the body are both arranged to be brazedor Specification of Letters Patent. Patent-gd Augfj 1916,

welded as indicated at'lOv to respective mewhose walls may accidentallyvary in thickness owing to the enameling and glazing processes to whichthey are subjected. When secured-in place it is to be understood that anenamel lining may be applied to the interior of a package and theexposed portion y of the nipple.

Obviously, changes in the details 'of construction may be made withoutdeparting from the spirit of my invention and I do not care to limitmyself to any particular form or arrangement of parts.

`What I claimis s l. The combination with a liquid contain-` ing packagehaving a wall formed with an outer metallic shell, an inner metalliclining, and insulating material separating the shell and lining, of abushing having a cy.

lindrical body provided with an exterior annular flange at the outer endand ar recessed outer end face with a central opening through the innerend face, the outer exterior liiange being adapted to bear against theouter metallic shell when the bushing is inserted in an opening throughthe wall of the package, and a nipple in'screw threaded engagement withthe central opening that is contained within the recessof the outer endface ofthe bushing, the inner end portion .of the nipple having anexterior an' Inular flange thatbears against Vthe lining on the interiorof the package and prevents contact between any liquid contents of thepackage with the insulating material.

2. The lcombination with a liquidvcontaining package having a wall withan apertured outer metallic shell, an inner metal lining 'having asmaller aperture alined with that of the outer metallic shell andinsulat-` ing .material separating the shell and lining havlng anopening substantially coincident with the outer opening of the voutershell, 105
